I'm getting the same error using gcc-9.1. Let me know if you want more info.
Found the following report [1] over the internet containing a patch that fixes the issue and makes ddd to compile. Please investigate its application on portage [1]: http://savannah.gnu.org/bugs/?41997

Patch worked for me too.
I'll pile on here too, I'd expect this bug to heat up now that gcc-9 is stable.
Created attachment 595922 [details, diff] The infamous patch itself Me too. Patch attached.
This was inadvertently fixed while doing https://bugs.gentoo.org/696934. I separated forward declaration from friend declaration though, so slightly different approach than proposed here.
